Definitions

  • the present invention relates to a method of decelerating the jumbo roll a paper of a board making machine during reel drum exchange and transfer of the jumbo roll.
  • the invention further relates to an apparatus for carrying out the method in which decelerating apparatus is connected to the arms provided for transfer of a jumbo roll.
  • Prior art braking devices are disclosed for instance in DE patent specification No. 24 27 466 and FI patent specification No. 51463.
  • the DE specification discloses an apparatus in which a brake drum disposed at both sides of the paper roll rotates with the roll. Brake levers connected by articulated joints at their lower ends to the bed are disposed on both sides of the brake drum. Brakes shoes, which are loaded against the drum by means of a pneumatic device arranged approximately in the middle of the levers, are connected to the upper ends of the brake levers via an articulated joint.
  • the Finnish patent specification discloses an apparatus for decelerating the winder of a paper or a board machine.
  • the decelerating device mainly comprises a braking arm disposed by the side of the winder to move synchronously with the center of the reel drum which allows deceleration of the reel drum and the roll around it in any desired phase.
  • the brake carriage comprises special coupling means for coupling the brake to the reel drum and brake means, i.e. a brake disc and brake blocks.
  • the apparatus operates in the following way: the rotating velocity of the coupling means is accelerated to be almost the same as the rotational velocity of the new reel drum and when the rotational velocity of the jumbo roll has decelerated to be the same as the velocity of the coupling means, the coupling is attached to the drum.
  • the rotation of the roll can be stopped at any desired moment by means of the braking means, i.e. by means of the brake disc and the brake blocks rotating with the coupling means.
  • the device according to this patent specification facilitates many operations which have previously been very difficult to perform, is still is very complex, it requires electronics, electric motors etc. This involves very high costs. Further the apparatus requires a remarkably large space by the side of the winder.
  • the apparatus according to the invention is further characterised by the feature that deceleration can be performed during the transfer of the jumbo roll.
  • deceleration can be performed during the transfer of the jumbo roll.
  • FIG. 1 is a general elevational view of the winder of a paper or a board manufacturing machine, illustrating the location of the decelerating apparatus according to the invention, in relation to the rest of the machinery;
  • FIG. 2 is a detailed side view of a preferred embodiment of a decelerating apparatus according to the invention.
  • decelerating apparatus 1 is located at the transfer device for the jumbo roll 2 (very large roll) of a paper of a board manufacturing machine.
  • the numeral 2 refers to a finsihed jumbo roll which has been wound around a reel drum 3.
  • bearing housings 4, on which the jumbo roll is supported on rails 5, are provided at the ends of the reel drum 3.
  • the decelerating apparatus 1 is connected via an articulated joint (pivot) to a bracket 7, which is fixed to the bed.
  • the decelerating apparatus itself comprises an arm 8, which is articulately connected to the bracket 7, and a brake shoe 9 swinging or pivotting in a vertical plane in the machine direction which shoe 9 is connected to the upper end of the arm 8 by an articulated joint or pivot connection.
  • a brake lever 10 is pivotally connected to the arm 8 and the other end of the lever 10 is provided with a brake shoe 11, which is substantially opposed to shoe 9 and which pivots in the machine direction.
  • the length of the brake lever 10 and the arm 8 is chosen to make the brake shoe 11, which is pivotally connected to the brake lever 10, clearly reach to the paper machine side of the reel drum axis when the jumbo roll is finished. Further, the dimensioning is chosen so as to maintain the brake shoes 9, 11 in contact with the counter surface of the reel drum the whole time when the jumbo roll 2 rolls along the rails 5 to a position over the bracket 7, which bracket 7 is mounted on the bed.
  • the brake lever 10 is connected to a bracket 12 of the arm 8 via a pressure medium cylinder 13 or a corresponding means by which the brake shoes 9, 11 are pressed towards or drawn away from each other.
  • the arm 8 is connected via a pressure medium cylinder 14 or a corresponding means to a body construction 15.
  • identical decelerating devices 1 are provided at both sides of the winder, which devices 1 preferably are connected to each other at the lower ends of their arms 8 with an adjusting rod disposed in the transverse direction of the winder.
  • the embodiment of FIG. 2 may operate, if required, with only one transfer cylinder 14 as the arms 8 on the opposite sides of the winder are connected to each other via intermediate rods 16, levers 17 and an adjustment rod 18 which is disposed transverse under the winder.
  • These means transmit a movement of the same size and direction as the movement of the arm 8, which is adjacent the cylinder 14, to the arm on the other side of the winder.
  • the levers 17 are fixed by a rigid joint to the rod 18 and by an articulated or pivot joint to the bed 6 via a bracket 19.
  • the decelerating apparatus 1 operates in the following way.
  • the brake shoes 9, 11 of the decelerating apparatus 1 contact the outer periphery of the end of the reel drum 3 or the casing surface of the reel drum thus decelerating the rotation of the jumbo roll 2.
  • This action rapidly causes a web loop to be formed which is guided to be wound around a new reel drum. Subsequently the web is cut.
  • the transfer cylinder 14 is pressurized to pull the jumbo roll 2 away from the winder.
  • the jumbo roll 2 can roll along rails 5 on its bearing housings 4 while the brake shoes 9, 11 during the whole time thereof, sustain full contact with their counter surfaces. This operation minimizes the time required for a reel drum exchange and also reduces the amount of paper or board wasted during the deceleration phase.
  • a most important feature of the apparatus according to the invention is that articulation or pivoting of the brake shoes 9, 11 at the ends of the arms 8, 10 and the brake levers allows decelerating the jumbo roll already while it is being transferred.
  • the levers of the decelerating apparatus can be either by the inner or the outer side of the rails 5 or that either the casing surface of the reel drum 3 or the outer surface of a toothed coupling can be serve as the brake surfaces on the reel drum side. Further, if these surfaces for some reason can not be used as brake surfaces, it is possible to provide for instance specific friction surfaces, for example, on the outer surfaces of the toothed coupling, whereby the brake shoes would, of course, have no need for friction surfaces.
  • the means 13 and 14 are in most cases pneumatic or hydraulic cylinders but they can be any means providing the same movement range.
  • the drive means 13 can in some applications be substituted by a lever arm articulated to the means 14 and connected to the brake lever 10, which produces the same operation as the means 13 in the described embodiment.
  • the transfer cylinder 14 or the corresponding means can be used for handling of rolls of different size, i.e. rolls at different distances from the Pope cylinders.
